Hi,

You can't create a 3D formula with Countif, it doesn't support it so here's
another apptoach

Create a list of your sheet names in a column ( I used B1:B4) like this

First
Sheet3
Sheet4
last

Then the formula

=SUMPRODUCT(COUNTIF(INDIRECT("'"&B1:B4&"'!A1"),"Y" ))

When competing hypotheses are otherwise equal, adopt the hypothesis that
introduces the fewest assumptions while still sufficiently answering the
question.

Good morning --

I'm shooting for a COUNTIF formula that will count text occurances across
multiple worksheets. I can get the formula to work if the data is on the
same worksheet but as soon as I go to multiple ones, it fails and I get a
'#VALUE!' error.

Here's the formula:

=COUNTIF(First:Last!A1,"Y")

Thanks in advance.
